To all whom it may concern:

Be it known that I, SIeMUND WILLNER, a subject of the German Emperor,-and a resident of Memphis, county of Shelby, and State of Tennessee,have invented certain new and useful Improvements in Apparatus forForcing Fluids into Wood, of which the following is a specification.

This invention relates to apparatus for causing chemicals and liquids topenetrate the interior of a piece of wood, and has particular referenceto devices for coloring the wood.

The main objects of this invention are to provide in a device of thisclass means for producing a variegated coloring to the wood in theinterior of a log by forcing coloringmatter of different shades orcolors into the grain of diiferent parts of the log and to provide animproved construction for such apparatus whereby the distribution ofcolors in the interior of the log may be controlled by the operator. Iaccomplish these objects by the device shown in the accompanyingdrawings, in which Figure 1 is a longitudinal section of a deviceconstructed according to my invention, a log being indicated in positiontherein by dotted lines. Fig. 2 is an elevation showing the formation ofthe gripping-face of one of the members for engaging the log.

The principal features of the device shown are the supporting-frame,gripping members I which are adjustable toward each other for engagingopposite ends of a log, the subdivisions of the gripping-faces of saidmembers into independent parts separated by sharp ridges adapted to havewater-tight engagement with the log, and means for supplyingcoloring-matter to each of such compartments independently of the othersand forcing such coloring-matter endwise through the grain of the log.

In the construction shown in the drawings the supporting-frame consistsof a bed-plate 3, having uprights 4 and 5 secured at opposite ends ofthe same. The uprights are preferably secured by bolts 6, having theirheads seated in slots of T-shaped cross-section to permit of adjustingthe uprights along the bed-plate. Mounted upon the bed-plate between theuprights are a pair of adjustable jacks 7, adapted to support a log inalinement with the uprights. The upright i has rigid thereon a head orgripping member 8. A

similar gripping member 9 is mounted upon a shaft 10, which has threadedengagement with the upright 5 for adjusting the member 9 toward and awayfrom the member 8. The opposed faces of the members 8 and 9 are eachprovided with a plurality of concentric annular depressions 11, whichare separated by annular pointed ridges 12. The crests of the ridges 12all lie in the same plane, so that all of the ridges which are opposedto the end of the log will form a water-tight joint therewith when thehead 9 is forced inwardly, so as to cause the ridges to penetrate theends of the log. Each of the depressions 11 communicates with a passage13,extending through the corresponding member. In the member 8 each ofthe passages 13 connects with an independent valve-controlled pipe. Eachof these pipes connects with a pump by means of which coloring-mattermay be independently injected into each of the depressions 11. Thesepumps are not shown; but it is preferred to have a separate pump foreach pipe, so that the grain of the log. which is in communication witheach of said apertures, may be subjected to an individual shade ofcoloring and all parts of the log may be simultaneously treated. Thevalves for independently controlling the pipes 14 are indicated at 15.The passages 13 in the member 9 all connect to an annular passage 16,and the mixed coloring-matter accumulating in such passage is conductedaway by a pipe 17 The operation of the device is as follows: Beforesubjecting a log to the coloring treatment, as in the herein-describedapparatus, it is usual to drive out the sap, so as to leave the pores ofthe wood empty. This may be accomplished by forcing suitable chemicalsthrough the wood before injecting the coloring-matter. The log is placedupon the supports 7 in a position of substantially central alinementwith the members 8 and 9, and the member 9 is then forced against thelog by rotating the wheel 18 until the ridge 12 becomes sufl'icientlyembedded into the ends of the log to form a water-tight partitionbetween the cavities formed by the depressions 11 and the ends of thelog. Coloring-matter is then pumped under pressure into each of thepipes 14:. The desired shade of coloring is obtained by passing liquidsof different colors into the various spaces 11. If the log is of lessdiameter than the member 8, then such depressions on said member whichare not completely closed by the end of the log are out 011' by closingtheir respective valves. The coloring-matter under pressure of the pumpsthen forces its way through the grain of the log following thesap-channels and accumulates in the passage 16 in the member 9. Thegeneral tendency of the liquid is to flow through the log in thedirection of the grain; but enough of the coloring-matter spreads in theinterior of the log to provide the proper blending of shades and colors.The double crests of the outermost ridges 12' engage the end of the logsof average diameter near their peripheries and serve to insurewater-tightness at this point by preventing splitting of the log.

It will be seen that numerous details of the construction shown may bealtered without departing from the spirit of my invention.

What 1 claim as my invention, and desire to secure by Letters Patent, is

1. In an apparatus of the class described, the combination of a framefor supporting a log, a member on said frame having a plurality ofdepressions in one face thereof, ridges inclosing said depressions andseparating each from the other, all of said ridges being adapted to havewater-tight engagement with one end of the log When said member isforced against the same and means for supplying liquid under pressure toeach of said depressions independently of the others. v

2. In an apparatus of the class described the combination of a frame forsupporting a log, a member in said frame having a plurality ofdepressions in one face thereof, pointed ridges inclosing each of saiddepressions and separating one from the other, said ridges beingsharpened and having their crests lying substantially in the same planeand adapted to penetrate the log when said member is forced endwiseagainst the same, means for forcing the log and member toward eachother, and means for supplying liquid under pressure to each of saiddepressions independently of the other depressions.

3. In an apparatus of the class described, the

combination of a frame for supporting a log, a member in said framehaving in one face a plurality of concentric annular depressions eachseparated from the other by a continuous ridge, each of said ridgesbeing sharpened at its crest and the crests of said ridges lying in thesame plane and adapted to penetrate the log when said member is forcedendwise against the log, and means for supplying liquid to each of saiddepressions independently of the others.

4. In an apparatus of the class described, the combination of a framefor supporting a log, a member in said frame having in one face aplurality of concentric annular depressions each separated from theother by a continuous ridge, each of said ridges being sharpened at itscrest and the crests of said ridges lying in the same plane and adaptedto penetrate the log when said member is forced endwise against the log,and individual valve controlled pipes for conducting liquid to each ofsaid depressions.

5. In an apparatus of the class described, the combination of a framefor supporting a log, a member in said frame having in one face aplurality of concentric annular depressions each separated from theother by a continuous ridge, each of said ridges being sharpened at itscrest and the crests of said ridges lying in the same plane and adaptedto penetrate the log when said member is forced endwise against the log,means for supplying liquid to each of said depressions independently ofthe others, and a ridge outside of the outer depression and having aplurality of sharpened crests lying in the same plane with each other.
